Cleaning, maintenance, and storage

Important
Pull out the power plug before doing any cleaning and maintenance work on the equipment. Risk of injury from electric shock! Wait until the equipment has cooled down completely! Risk of burns! Always depressurize the equipment before carrying out any cleaning and maintenance work! Risk of injury!

Cleaning

• Keep the equipment free of dirt and dust as far as possible. Wipe the equipment with a clean cloth or blow it down with compressed air at low pressure.
• We recommend that you clean the equipment immediately after you use it.
• Clean the equipment regularly with a damp cloth and some soft soap. Do not use cleaning agents or sol-vents; these may be aggressive to the plastic parts in the equipment. Ensure that no water can get into the interior of the equipment.
• You must disconnect the hose and any spraying tools from the compressor before cleaning. Do not clean the compressor with water, solvents or the like.

Maintenance work on the pressure vessel/condensed water (Fig. 1)
Important!
To ensure a long service life of the pressure vessel (7), drain off the condensed water by opening the drain valve (9) each time after using.  Release the vessel pressure first (see 10.8). Open the drain screw by turning counter- clockwise (looking at the screw from the bottom of the compressor) so that all the condensed water can run out of the pressure vessel. Then close the drain screw again (turn it clockwise). Check the pressure vessel for signs of rust and damage each time before using. Do not use the compressor with a damaged or rusty pressure vessel. If you discover any damage, then please contact the customer service workshop.

Safety valve (Fig. 2/Pos. 16)
The safety valve (16) has been set for the highest per-mitted pressure of the pressure vessel. It is prohibited to adjust the safety valve or remove its seal. Actuate the safety valve from time to time to ensure that it works when required. Pull the ring with sufficient force until you can hear the compressed air being released. There lease the ring again.

Checking the oil level at regular intervals (Figure 10)
Place the compressor on a level and straight surface. The oil level must be between the MAX and MIN marks on the oil level window (18). Oil change: we recommend SAE 15W 40 or equivalent. The original oil filling must be changed after 100 hours in operation; thereafter the oil must be drained and replaced with new oil after every 500 hours in operation.

Changing the oil (Figure 10)
Switch off the engine and pull the mains plug out of the socket. After releasing any air pressure you can unscrew the oil drain plug (20) from the compressor pump. To prevent the oil from running out in an uncontrolled manner, hold a small metal chute under the opening and collect the oil in a vessel. If the oil does not drain out completely, we recommend tilting the compressor slightly. When the oil has drained out, re-fit the oil drain plug (20). Dispose of the old oil at a drop-off point for old oil. To fill in the correct quantity of oil, make sure that the compressor stands on an even surface. Fill new oil through the oil filler opening (14.1) until it comes up to the maximum level. This is marked with a red dot on the oil level window (18) (Fig. 10 pos. 18.1). Do not exceed the maximum filling quantity. Overfilling the equipment may result in damage. Reinsert the oil sealing plug (14) into the oil filler opening (14.1).

Cleaning the intake filter (Fig. 12, 13)
The intake filter prevents dust and dirt from being drawn in. It is essential to clean this filter after at least every 300 hours in service. A clogged intake filter will decrease the compressor’s performance dramatically. Open the thumb screw (G) to remove the intake filter. Then pull off the fi lter cover (J). Now you can remove the air filter (L) and the filter housing (K). Carefully tap out the air filter, filter cover and filter housing. Then blow out these parts with compressed air (approx. 3 bar) and reinstall in reverse order.

Storage

Important
Pull out the mains plug and ventilate the equipment and all connected pneumatic tools. Switch off the compressor and make sure that it is secured in such a way that it cannot be started up again by any unauthorized person.

Important
Store the compressor only in a dry location that is not accessible to unauthorized persons. Always store upright, never tilted!

Releasing excess pressure
Release the excess pressure by switching off the compressor and using the compressed air which is still left in the pressure vessel, e.g. with a compressed air tool running in idle mode or with a blow-out pistol.
